The dolphin trail is a mass public art exhibition for Perth Children’s Hospital’s mental health awareness initiative, The Big Splash, that encourages people to have conversations about adolescent mental health.

One of the 36 dolphins titled ‘Go Bananas!’ designed by artists Anna Pesti and Devan Job, has been installed outside the Perth Concert Hall.

A mobile phone application will be available so the public can locate each dolphin and get information about the artist and mental health.

The exhibition runs until March 4, after which each sculpture will be auctioned with proceeds going to the Perth Children’s Hospital’s Child and Adolescent Mental Health Unit.

Perth Children’s Hospital Foundation chief executive Carrick Robinson said the main message of The Big Splash was “you are not alone”.

“There are many people and organisations there to support young people facing mental health problems – and with the help of Perth Concert Hall this important message can be spread further to young West Australians and their families.”
